IMPROVEMENT lN COOKING-RANGES.

Specification forming part of Letters Patent No. 129,454, dated July 16,1872.

Specification describing a certain Improvementin Oooking-Ranges,inventedby CHARLES H. BLANOHARD, of the city and county of St. Louis and Stateof Missouri.

My invention relates to a combined warming oven and shelf that is placedabove and on a portable wrought-iron range; and consists in thecombination-of such heater with a range, substantially as described.

The drawing is a perspective view of my improvement.

A is the range, from whose back extends upward a plate, B, having wingsO forming the end supports of the warming-oven or hot closet D, of whichE are the doors. F is a vertical pipe extending through thewarming-chamber, the stove-pipe passing through the said pipe.

I am aware that ovens have heretofore been placed at a higher elevationthan a stove-top, and in the line of the escaping smoke, (on rangesinclosed in brick walls, but not on portable wronght-iron ranges,) andalso that an open heating-shelf has been applied in the same position asmy warming-oven; but my arrangement differs materially from both ofthese. It difiers from the first in forming no impediment to theescaping products of combustion, having no communication with theinterior of the ordinary stove-pipe, and cansing no deflection of theflue-ways. It also differs radically in construction from said ovens. Mywarmer differs from the open shelf in that it has a closed chamber,wherethe matters becoming heated are preserved from dust and evaporationchecked. The shelf heretofore used has proved a great convenience, butis defect ive in that, as it is in the main course of the dust and ofany smoke arising from an open hole, victuals are liable to become dryand dusty when placed thereon.

I claim as my invention- The heater D, having no communication with theinterior of the smoke-flue or chimney, and provided with a verticaltube, F, extending entirely through the warming-chamber and situatedimmediately above the stovepipe hole, through which tube F the stovepipepasses directly, thereby more efl'ectually heating the warming-chamberand causing no deflection of the flue-ways, as set forth. I

In testimony of which invention I have hereunto set my hand.
